Gross to Net Media Advertising Formula
The following equation is used to calculate the net media cost from gross.
- Where NMC is the net media cost ($)
- GMC is the gross media cost ($)
- CR is the commission rate charged by the advertising company for placing your ads (%)
Multiply gross by (1 − CR/100), where CR is entered as a percentage. Reverse by dividing net by that factor. A commission on gross differs from the same percentage markup on net; see the 4As/ANA compensation model guide. Use your negotiated basis and rate.

What is Gross and Net Media Advertising?
Definition:
Here, gross media cost includes the commission deducted to reach net media cost. Other compensation models can use different definitions.
Under this model, net media cost equals gross media cost less the gross-based commission. Taxes, platform fees and other negotiated charges are excluded unless already reflected in your entered amounts.
How to Calculate Gross to Net Media Advertising?
Example Problem:
The following example outlines the steps and information needed to calculate the net cost of advertising from the gross cost.
First, determine the gross cost. For this example, the gross media cost is found to be $1,000.00.
Next, determine the commission rate. The commission rate for this example is 10%.
Finally, calculate the net media cost using the formula above:
NMC = GMC * (1-CR/100)
NMC = 1000 * (1-10/100)
NMC = $900.00
